Technical information for B-lubricator
Noise level
The noise level is less than 70 dB(A)
The lubricator is capable of pumping oils and other fluids with a maximum viscosity of approx. 600 cSt at 40 °C. High viscosity oils and fluids may have to be pre-heated before they can be pumped.
Plunger diameter 9 mm (standard)
Max feed per pump stroke:0.30 cm³
Max continuous back-pressure:12 MPa (1,700 psi)
Max intermittent back-pressure:30 MPa (4,400 psi)
Plunger diameter 7 mm
Max feed per pump stroke:0.18 cm³
Max continuous back-pressure:20 MPa (2,900 psi)
Max intermittent back-pressure:30 MPa (4,400 psi)
Adjusting feed
Maximum feed per pump stroke of the plunger is equivalent to approx. 0.30 cm³. Feed is reduced approx. 0.05 cm³ for each anti-clockwise turn of the set screw. To ensure accurate adjustment, the set screw is stopped each 1/4-turn by a spring-loaded ball pressing into grooves in the set screw.
Turning the set screw a 1/4-turn thus reduces or increases the volume fed by approx. 0.012 cm³. We recommend not to adjust the set screw more than about 5 turns, a setting gives approx. 0.03 cm³ (one drop of oil) per stroke. You can check the feed by counting the number of drops passing the sight glass during one minute. Multiply this by 0.03 cm³ and you obtain an accurate output.
